This analysis indicates an approximately 97% cost reduction using the ND-ELO thin-film GaAs solar cell integrated with a 6° tilted CPC compared with substrate-based cells and an 89% reduction.
They estimate that in 2027 the cost of PVs will reach the same as cost of coal, but if co-benefits are taken into account, the cost can be reached earlier, in 2023. Sensitivity analyses show a heavy influence of the damages cost.
Applying a bottom-up methodology, we analyzed the costs associated with mc-Si and thin-film modules and systems as a function of module area. We calculate a potential for savings of up to $0.04/W, $0.10/W, and $0.13/W in module manufacturing costs for mc-Si, CdTe, and CIGS respectively, with large area modules.

6 FAQs about [GaAs photovoltaic panel cost analysis]
What is a GaAs based solar cell used for?
Probes, Satellites and Other Space Objects Probably the most extensive use has been made of GaAs-based solar cells on space satellites, probes, and other objects, primarily because of the potential risk of gamma radiation, where GaAs also show higher resistance.
How much does a GaAs cell cost?
Li et al. state that compared to silicon, the prices of GaAs cells are up to ten times higher . In contrast, the prices of silicon cells are very affordable today. Since 1977, when the cost per watt was around 76 dollars, it is now approximately 36 cents .
Can a manufacturing cost analysis relevant to Photovoltaic Cells fabricated on silicon?
A Manufacturing Cost Analysis Relevant to Single- and Dual-Junction Photovoltaic Cells Fabricated wtih III-Vs and III-Vs Grown on Czochralski Silicon. Presentation, Golden, CO: National Renewable Energy Laboratory.
How do GaAs-based solar cells work?
For GaAs-based solar cells, performance can also be tuned by layering, where one solar cell can contain up to eight thin layers, each absorbing light at a specific wavelength. Such photovoltaic cells are called multi-junction or cascade solar cells. They use tandem fabrication, so they can also be found under the name tandem cells.
Why are thin-film GaAs solar cells better than substrate-based solar cells?
Furthermore, the unique geometry of thin-film GaAs solar cells mounted on a heat-sinking metal layer enables operation at or near room temperature without active cooling, even for concentration factors approaching 4×, representing a reduction of over 40 °C compared to substrate-based GaAs solar cells.
Can GaAs solar cells be grown by vapor-phase epitaxy?
